Abstract

Composites of 1 % Mn-doped magnesium aluminosilicate and aluminogermanate were synthesized by the conventional sintering method, and the luminescence properties including photoluminescence, radioluminescence, and thermally stimulated luminescence were investigated. The photoluminescence spectra of composites showed the broad and sharp emission peaks at around 650 nm due to Mn²⁺ and Mn⁴⁺. The radioluminescence and thermally stimulated luminescence spectra of the synthesized samples showed only the broad emission peak at around 650 nm. The X-ray image by thermally stimulated luminescence was clearly observed using synthesized composites.

锰掺杂铝硅酸镁与锗酸铝复合材料的发光性能

采用常规烧结法合成了掺1% mn的铝硅酸镁和锗酸铝复合材料，研究了其光致发光、辐射发光和热激发发光性能。复合材料的光致发光光谱显示，由于Mn2+和Mn4+的作用，复合材料在650 nm附近有宽而锐利的发射峰。合成样品的辐射发光和热激发发光光谱仅在650 nm左右出现宽发射峰。利用合成的复合材料，可以清晰地观察到热激发发光的x射线图像。

期刊介绍： The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
